Answer: ENERGY: A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers. These levels are used to describe ecosystem structure and dynamics.
MATTER: When one organism eats another, the matter, or carbon, nitrogen, and other essential elements, are transferred from one to the other. These elements move from the producers, to the consumers, and eventually to the decomposers, cycling the matter through the ecosystem.
Explanation: look up
The amount of a
substance can be converted into grams of that substance by using the molar
mass. It is a physical property of a substance which describes the mass per
mole of the substance. The molar mass of CH3OH is 32.04 g/ mol. Multiplying the
given amount of CH3OH with the molar mass will yield to the mass of the substance.
<span>9.09x10^24 molecules CH3OH ( 1 mol / 6.022x10^23 molecules) (32.04 g/mol) = 483.63 g CH3OH
Dividing the molar mass of N2O which is 44.08 g/mol to the given amount will yield to the number of moles.
0.183 g N2O / 44.08 g/ mol =0.0042 mol N2O</span>
Answer: 1.284M NH3
Explanation: (12.23 grams)/(17.0 gramms/mole) = 0.7191 moles
Dissolved in 560.0 ml (=0.5600L)
(0.7191 moles)/(0.560L) = 1.284M (4 sig figs)
